"I have an King Arms M4 CQB and was so disappointed with the 50rds mag that comes with the rifle, I also tried an G&P 50rds mag and had the same issue, the leaking, so after a few researches I decided to buy the G&P 39rds PTS Magpul mag and now I am pretty convinced that this is the top of theine on GBB mags. I just test it today and I was able to shoot 3 full magazines plus a few more shots with just one refill of gas on propane for a total around 120 bb's without refill it again. I do recommend this magazine, also Im planning to buy a few more.

"These magazines are the absolute bomb! They operate perfectly, no leaks and very economical on gas. But don't drop them however, I dropped one by accident and now it leaks.. Anyway, I would recommend these over any of the others sure they may be a bit pricey, but its worth every cent. They just need slight sanding on the sides to fit into the magazine well properly and they are good to go.

"This is the best magazine for king arms, wa or anything that these will fit. They feed flawlessly, less prone to leaking(compared to other mags). Also they're cheaper than other mags out there. Not to mention they look great!

"Just got the mag in today and i have to say compared to those king arms mags these are freak'n awesome! I'm running it in my king arms gbbr and it works like a dream but i do have one issue with it. The little ball like thing that pushes the BBs up into the feed lip is larger than your standard one compared to a G&P or king arms one. Now this isn't really a bad thing because i think this contributes to the fact that it doesn't jam or misfeed at all but when the mag is empty and the bolt is locked back remove the mag before you release the bolt because if you leave it in the ball that pushes the bb up will get snagged by the loading nozzle and chip it. No big deal though because you take the mags out when they are empty anyway. I do not know if the same problem exist in the G&P or WA models because i do not own one but king arms is based off of those.

Pros:

Able to do a full auto mag dump

probably get 2 to 2 1/2 mags worth in one fill of gas (when firing in semi).

in other words this mag is super gas efficient!

Very solid construction

Cons:

other than what i said on top nothing at all really

NOTE* i bought this to match my Dark Earth furniture on my gun but was a little hesitant because the pictures make it look like an extremely bright tan but do not let that fool you because it matches my dark earth furniture just fine. (Im assuming they used flash while taking the pictures which make the mags look really bright).

"I currently have two of these mags for my g&p WOC challenge kit m4 and they work amazingly! They feed very well and they are super durable( they are metal) . I've only had one problem with them. Since the mags are built in 3 separate chunks with big o- rings between, there is a big screw that hold it all together. My mags leaked a tiny tiny bit out one of the cracks and to fix u just have to fake the bottom plate off, pop the pin out that holds the grey lever on, then the screw is revealed. Tighten a lot to hold the mag together tighter. I did that and no more leak. The fill valves are very nice and have o rings so they don't blow gas everywhere. All in all these mags are very nice and work great. Best mags I've used and need to get more.

"I have 2 more on the way, the first one I used for the G&P WOC Challenge kit, had to file a little off my magazine release, after that, worked great.... OTHER Than leaking out of the box.... Found out these are easy to take apart, I recommend oiling them if they leak on you, bought bulk O Rings for these as time goes on. Still recommend if you are handy.

I bought a couple more of these mags for my G&P WOC challenge kit. Compared to the G&P PMAG I bought in October 2013, these new ones no longer have the Magpul PMAG30 PTS Simulation trades on the body and floorplate. I didn't notice that on the product page but Evike does have the correct pictures. As far as functionality, one of the mags leaked right out of the box when filled. The body of these mags is a 3-piece design that is held on by a long screw that goes in from the bottom. There is an o-ring in-between each section. Having experience with these mags before I took the leaky mag apart and tried lubing the o-rings but that didn't work. I then started swapping body sections with the other new mag and found that when I swapped the middle section between both new mags, the previously leaky mag was barely leaking but only if I bent the mag with my hands instead of just sitting there. When taking both mags apart, I noticed that the good mag took extra effort to undo the screw compared to the leaky mag. I wasn't able to get the torque needed with just a flathead screw driver so I resorted to using a ratchet with a 1/4&#34; socket and then using a screw driver bit to tighten the magazine body screw. I'm not sure if it was the mag body section swap or the tightening the screw down more that fixed the leak, or if it was a combination of both but I was able to get it to be leak free. Because of the slightly leaky mag right out of the box I'm going to deduct 1 star. Overall these are good mags. The weight is realistic compared to a loaded real steel mag. The design is good where the floor plate protects the fill valve. They are efficient: on slow controlled fire I can get 120rds out of one fill. Doing 2 or 3 rds bursts in SEMI at 1 second intervals I can get 80 to 90rds out of one fill. Also, the 39 rds is pretty good for a GBBR.

"These are the only magazines I use, mostly because other ones are out of stock, but these ones are also probably easier to maintain as well.
Let's start from the top to bottom for pros:
-feed lips are metal, no wear with the original G&P bolt.
-fit great in hand and just feel natural reloading
-have base plates on the bottom to protect the fill valve or for mag pulls.
-retain gas EXTREMELY well, if you take care of them!
cons:
-o-rings eventually popped out, have to buy the moondog ones to replace them.
-mine have a hairline crack on it, though it doesn't leak it worries me
-paint on the back has worn down completely, just file down the back of your magwell to help stop it.
-you have to tighten these A LOT after you put them back together, unless if you have a bit of man-power, use a drill and slowly turn it with a wide enough bit to tighten it. Mine used to leak, but after using some man-power, they're tight enough that they do not leak.
overall: would recommend these for your GBB, good price compared to having to buy ones from over seas or waiting for G&P WA mags to come back in stock, they also have a nice look, since they're made by Magpul of course. Reason for 4/5 is because of earlier lack of man-power.

"These are great magazines, and are much less expensive than Pro-Wins. I have had no trouble whatsoever using these in my G&P WOC build. They have a fair amount of heft to them and weigh a little more than a fully loaded real-steel magazine- I'd say between 50-75 grams more.

I prefer these to the standard STANAG style G&P magazines because their design allows you to quickly address any internal leaks by tightening the screw that holds the three sections of the magazine together (located under the spring-latch that holds the Magpul baseplate on).

Make sure to keep the internal and inlet/outlet o-rings lubed and this magazine is sure to perform well. On a good day I can easily let off 4-5 loaded magazines (30 rounds ea.) on Semi with one fill of propane.

"someone needs to get on the quality control with these mags, I love the look of them and they are great when they work but I bought 3 of them and 2 leaked straight out of the box, not from the valve like most gbb mags but out of the side of the body due to the 3 piece body design. I don't mind working on things like this and solving the problem myself because its usually just a loose screw but it would of been nice having 3 more functional mags to play with this weekend. feels great in your hand though.

by John F. on 11/14/2013

"I suppose I could start by saying that these mags feel great, they have the weight and heft of a fully loaded RS 552 mag, however, I am disappointed because I bought two of these mags, one leaked after only three uses, and the other leaked right out of the box, they both leaked from the top seal (O-ring) and the last one I got actually leaked from the output valve, I'm hopping that 'soaking' it in silicone oil will fix that.

Would I recommend it?
Yeah, sure. If you don't mind repairing/changing the original O-rings.

"I received one of these mags with a G&P challenge kit I bought. After assembling the kit, i focused my attention on the magazine. These mags are advertised to hold 39 rounds, yet mine that i received only holds +-25 rounds. if you try and add more than this then the follower, gets jammed and will not feed. I don't know if this is my specific mag, or a manufacture's problem.
Pros:
-Good Gas efficiency
-Looks awesome
-Feeds well

"Amazing at first. I bought four of these mags, and I loved them for about four months. Then three mags started leaking. I bought a ton of o-rings and never got a good seal again. I just tried to caulk them shut. I have no clue if that will do it.

"I wasted a lot of money on poorly manufactured G&P gas blowback garbage this year. The G&P GBBR VPR rifle is garbage and these magazines are garbage. If you want a well-built GBBR, buy a KWA LM4 or even better the PTS model.

Also, let me be clear: these are not Magpul-built magazines. They may look like Magpul, but they are not.
